    Slots with i2C

    The RTC stops seconds counting on the clock readout. I'm trying to throw my memory back that far, to what I tried. I remember getting some ideas from here, of what other people tried as well. I few of those ideas would prevent a total lockup of the RTC data. But i assume because its...

    Slots with i2C

    Unfortunately no. I had built on this project and the memory usage got greater as I went along. A flag interrupt is already used elsewhere. And the hint pins are already hard wired in this project to other items. To rewire it, is more hassle than its worth.. Easier to just remove Slot 1 clock...

    Yes it is.

    Slots with i2C

    I was working on a project up to October last year, that contained the use of two slots on a 28X2. Slot 1 contained a full function clock/alarm. And slot 0 monitored/controlled dozens of I/O's. Which required continuous scanning of those inputs. The issue I have experienced, is the i2C bus...

    Potentiometer vs. Button

    I'm not an expert by a long shot. But something like this should work. #Picaxe 08m2 Setfreq M32 Symbol Duty = w0 Symbol Intensity = C.2 Symbol Up_sw = PinC.3 Symbol Down_sw = PinC.4 Main: PWMOUT pwmdiv16, Intensity, 99 ,0 Duty = 0 Do If Up_sw = 1 then Duty = Duty + 10 Max...

    Measure current on 12V line

    When it comes to sensing load current for a motor drive or actuator. There are some things to take into account. Which your code needs to handle. * The drive current * The overload current * The impulse startup current of the motor and gearbox assembly (which can be up to 4x greater than in...

    Measure current on 12V line

    Its on the panels to the charger side. Near the panels. Which is why I made the electronic fuse. Because solar panels don't produce a high impulse current when shorted, like a battery does. Which makes it impossible for a solar panel to blow a fuse or trip a circuit breaker in any short amount...

    Measure current on 12V line

    Its solar panel terminology. IMP = Current Maximum Power ISC = Current Short Circuit (which is generally an Amps or so higher than IMP) I never drew a circuit as such. It was just drawn on a piece of paper at the time. But I can give a run down of its operation. Plus here is a picture of the...

    Measure current on 12V line

    Now days there are many breakout boards with either a hall or shunt, that have a current sensor chip on board. This makes using them reasonable easy. I also have used many of these H bridge driver. Which have their own inbuilt shunt for load sensing. I would say my most over complicated picaxe...

    Measure current on 12V line

    I often use either Hall or Shunt current sensing on my picaxe projects. Its helpful for motor load sensing. Or as you're using it for.. A secondary means of detecting if the device is operating, and not just a high output state from the mC. Depending on the voltage scaling from the current...

    Are Rev-Ed & Picaxe missing out??

    I realize that this forum is provided by Rev.Ed and it does an awesome job of bring people together. But I also believe that this thread is needed for Rev.Ed's benefit, so they can see how many of us are loyal to Picaxe, but also long for it to evolve and keep up. I too admit that I use...

    AXE133 display problem

    I've experienced the lines flipping before. I tied it down to initialization problems. This particular display had seen stacks of ON time. I found that I had to increase the Power stabilization time as high as 900mS. And found it was beneficial to even increase the Pause time after sending...

    ReadADC and Comparator off the same pin

    Thanks (y) You mean to both questions?

    ReadADC and Comparator off the same pin

    Hi people, Just a bit of advice needed. I have a sensor connected to Pin b.4, ADC 6, Comp 1, on a 20X2. I wish to use that pin for a read ADC10 and a Comparator interrupt, from that same sensor. Is this permissible? I was also wondering if its not a problem to issue the CompSetup command at...

    Surely a PICAXE could be shoehorned in somewhere

    I do get your meaning. I'm not a Youtube creator. But have thought about posting a few of my projects online. So as to show people what Picaxe can do. But.. I'm not a real, look what I have done, type person. And my coding style rather abstract, and not orthodox, as the better codes here. Plus...
